The group has installed Poswatch software across its 106 store estate as part of its ongoing range review.
Brand development manager Mike Igoe said the new system enabled much faster analysis of EPoS data from individual stores which would lead to quicker decisions about product mix, layout and merchandising.
The software would be useful in the drive to improve availability by identifying which products were likely to sell out more quickly in which stores. And the system can improve promotions through clearer links between product purchases.
Igoe said: “By using software tools like this we can find associations not commonly thought of, such as fathers buying nappies as an emergency purchase and getting cans of Carling at the same time.”
